Natsume was asked by Aunt Tako to go to the next town to buy something, and on the way back, she cut a short path, but got lost. On the way, a one-horned yokai chased after another yokai (in fact, two yokai, it seems to use a combination technique, it looks like a yokai), the chased yokai is scattered by the one-horned yokai, a yokai is bounced into the tree where Natsume is hiding, and Natsume, who is frightened by the unicorn yokai, immediately punches away the unicorn yokai. Natsume can't stand to be frightened, and every time she is frightened, it is the youkai who are injured.
Natsume was also bounced off and slid down the hill and fainted; the two yokai who were chased regarded Natsume as Suzuko, and it seems that they were also yokai who once knew Suzuko.
The two take the fainting Natsume to the cave where they live, and when they wake up, they mistake him for Suzuko and tell Natsume why they were chased by the one-horned youkai. They were going to the Wangcui Rock to get the spring water, and the one-horned monster was there to monopolize the spring water. Every twelve years, a spring of water will gush out from WangcuiYan that can increase the power of the youkai.
When Natsume tells them that he is not Natsume Suzuko, but her grandson, he is also thought by the two youkai that he has just hit his head, causing him to be unconscious.
The Yokai couple recounts their encounter with Suzuko.
As evening approached, Natsume was leaving, so the yokai couple took Natsume out of the forest and said goodbye to him.
When the drunkard cat teacher hears what happened to Natsume, he asks Natsume to take him immediately, but when Natsume refuses, he also coddles him.
By the time they arrived, there were already other yokai starting the banquet.
The Yokai couple taught Natsume to make wine glasses.
The wine glass did not last until the evening and disappeared, and the banquet ended.
In the mouth of the cat teacher, he learned that the day when the water gushed out of Wangcuiyan happened to be today, so Natsume rushed back, but when they arrived, the yokai couple had already left; Natsume asked the cat teacher to take him to Wangcuiyan.
When they arrived, the yokai couple had already begun to fight the unicorn yokai, and soon lost the battle, and then the cat teacher who arrived drove the unicorn yokai away.
After the Yokai couple obtained the water, Hinata planned to make their own wine glasses with Hatuna; they had been making wine glasses for others all their lives, but they had never made wine glasses for themselves.
